Functioni

Involved in acetate metabolism.By similarity

Catalytic activityi

Acetyl-CoA + phosphate = CoA + acetyl phosphate.

Pathwayi: acetyl-CoA biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes acetyl-CoA from acetate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Acetate kinase (ackA), Acetate kinase (ackA)
  2. Phosphate acetyltransferase (pta), Phosphate acetyltransferase (RK59_006045)
This subpathway is part of the pathway acetyl-CoA biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes acetyl-CoA from acetate, the pathway acetyl-CoA biosynthesis and in Metabolic intermediate biosynthesis.
